Improving our ConstructorΒΆ
Our constructor so far can only create points at location (0,0). To create a point at position (7, 6) requires that we provide some additional capability for the user to pass information to the constructor. Since constructors are simply specially named functions, we can use parameters (as we’ve seen before) to provide the specific information.
We can make our class constructor more general by putting extra parameters into the __init__ method, as shown in this codelens example.

Now when we create new points, we supply the x and y coordinates as parameters. When the point is created, the values of initX and initY are assigned to the state of the object.
